Tools, Systems, and Methods for Remodeling Tissue
First Claim
1. A tool for treating a mitral valve annulus of a heart, comprising:
- a substantially rigid handle comprising proximal and distal ends and having a length sufficient to access a mitral valve annulus from outside a patient'"'"'s body via an opening in the patient'"'"'s chest;
a reshaping element extending from the distal end of the handle and terminating in a substantially atraumatic distal tip, the reshaping element being directable to a curved configuration defining a radius of curvature to extend partially around the mitral valve annulus for remodeling tissue surrounding the mitral valve annulus.

Abstract
A tool for remodeling a tissue annulus includes an elongate handle and a reshaping element on a distal end of the handle. The reshaping element may be directable between a first configuration to facilitate direction through a tissue annulus, and a second curved configuration to remodel tissue adjacent the tissue annulus. The tool may be used for treating a tissue annulus within a patient'"'"'s heart, e.g., by introducing the reshaping element through the tissue annulus, and manipulating the tool to reshape the tissue annulus substantially to a contour of the reshaping element. The reshaping element may support the tissue while a prosthesis is secured to the tissue annulus, or the reshaping element may itself be secured to the tissue annulus and released from the tool.
